Answer:

since the denominators are the same we add 3 and 7 in the numerator to get 10/8 or 1 2/8, and we can simplify to 5/4 or 1 1/4.

Find the length of BC. Explain how you got it, please! Thanks!

Vinvika [58]

Answer:

BC = 30.73

Here,

$\sf \frac{AB}{BQ} = \frac{CD}{DQ}$

so first solve for QD

$\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}$

$\sf \hookrightarrow 32(DQ)} =19.2(15)$

$\sf \hookrightarrow 32(DQ)} =288$

$\sf \hookrightarrow DQ =9$

Hence, QD = 9

Now! using Pythagoras theorem,

CD² + BD² = BC²

19.2² + (9+15)² = BC²

BC = √368.64+576

BC = 30.73499634

BC = 30.73 ( rounded to nearest hundredth )

Ephraim took a friend for a birthday dinner. The total bill for dinner was $30.29 (including tax and a tip). If Ephraim paid a 2

notka56 [123]

Answer:

$x= 30.29 (1-0.223) = 23.54$

Ephraim paid a 22.3% tip, what was his bill before adding the tip?

23.54

Step-by-step explanation:

For this case we assume the following notation:

$T= 30.29$ represent the total paid for the dinner

x represent the amount before adding the tip

f =0.223 represent the fraction of the total amount destined to the tip

Based on this we can create the following relationship between T and x:

$T = f*T + (1-f)T = f*T + x$

And we can solve for x from the previous equation like this:

$x = T - f*T$

Taking T common factor we got:

$x = T (1-f)$

And if we replace we got:

$x= 30.29 (1-0.223) = 23.54$

And the amount destined to the tip would be $fT = 0.223*30.29=6.75$

And if we add the two values we see that:

23.54+6.75 = 30.29 representing the total cost.

So then the correct answer for the question:

Ephraim paid a 22.3% tip, what was his bill before adding the tip?

23.54

Figure ABC is to be translated to Figure A'B'C' using the rule (x, y) → (x−3, y+4).

REY [17]

Answer:
(-2,5)

Explanation:
We are given the following translation rule:
(x,y) .............> (x-3 , y+4)
This means that:
new x coordinate can be found by subtracting 3 from the old x coordinate
new y coordinate can be found by adding 4 to the old y coordinate

From the figure, we can note that the coordinates of point A are (1,1).

Applying the above translation rule, we can get the coordinates of A' as follows:
x coordinate of A' = x coordinate of A - 3
x coordinate of A' = 1 - 3 = -2

y coordinate of A' = y coordinate of A + 4
y coordinate of A' = 1 + 4 = 5

Based on the above, the coordinates of A' would be (-2,5)

Hope this helps :)
